Works for any hand/draw.
Yes, these percentages are easy to figure out, but how do you translate them into correct decisions based on pot odds? If I have a 36% chance to hit a flush with 2 streets to come and facing a 2x pot-size bet from villian, how do I use the 36% figure?

OK - One way to do this would be to use the odds-chart that I found recently. It says that I actually have a 35% chance for the flush, which translates to 1.86:1. So I would need pot odds of 1.86:1 or greater (ex. 2.3:1) to call the turn. If I miss the flush on the turn, the odds change and the chart says that I need 4.11:1 pot odds to call a bet on the river. Correct?

EDIT: I think I said this wrong. AFAIK, it should read 'The chart says that I have a 35% chance for the flush, which translates to 1.86:1 Hand Odds. So I would need pot odds of 1.86:1 or less (ex. 1.5:1) to call the turn. In simpler terms, as stated below, Hand odds should be greater than Pot odds to justify a call. Also, implied odds and villian reads, etc. should be a factor.

I use Poker Office, which displays the pot odds on the table, so I should be ok using that and the odds chart. I can repost the chart if needed. Robb may have been the original source of the chart.
